The Mechanism and Control Technology of Thawing Water Disaster Caused by the Bedrock Freezing Construction

With the freezing depth of mine shaft increasing, freezing construction thawing water disaster was increasingly prominent. It took the Binchang Hujiahe mine geological conditions of Shanxi Coal and Chemical Industry Group as example, analyzed the mechanism and harmfulness of deep mine freezing construction thawing water disaster, then it summarized the present control methods, introduced the new technology of Hujiahe mine thawing water disaster prevention, which had important reference value for solving shaft thawing water disaster under the similar conditions.
